Use PEMDAS to get $t = 1.37$ $t=1.37$

To solve this problem, the best way would be to use PEMDAS.

Because our variable, $t$ $t$ , is being divided by $2$ $2$ , we need to multiply both sides by $2$ $2$ .

$\frac{t + 3.95}{2} (\cdot 2) = 2.66 (\cdot 2)$ $(t+3.95)/2 (*2)=2.66 (*2)$
$t = 3.95 = 5.32$ $t=3.95=5.32$

We'd then subtract $3.95$ $3.95$ from both sides, so $t$ $t$ would be isolated.

$t = 3.95 - 3.95 = 5.32 - 3.95$ $t=3.95-3.95=5.32-3.95$
$t = 1.37$ $t=1.37$

How do you solve t+3.952=2.66\frac { t + 3.95} { 2} = 2.66?
